Abstract
The spray head for a pre-rinse assembly includes a discharge cover having a plurality of ports for discharging water and a diffuser within discharge cover having a circumferential wall with at least one slot for directing a jet of water onto the fins of a rotatable impeller within the diffuser. The impeller has a plurality of tabs disposed relative to the ports whereby a respective tab momentarily covers a respective port to prevent passage of water therethrough during rotation of said impeller thereby effecting a pulsating stream of water through a respective port.
Claims21
A spray head for a pre-rinse assembly comprising
- a discharge cover having a plurality of circumferentially disposed ports for discharging water therethrough;
- an impeller rotatably mounted within said cover, said impeller having a plurality of circumferentially disposed fins thereon and a plurality of tabs disposed circumferentially thereof and transverse to said fins, said tabs being disposed relative to said ports whereby a respective tab momentarily covers a respective port to prevent passage of water therethrough and from said discharge cover during rotation of said impeller while the other of said tabs are spaced from the other of said ports to allow passage of water therethrough and from said discharge cover;
- and
- means within said cover for directing at least one jet of water onto said fins of said impeller to effect rotation of said impeller within said cover and for subsequent passage out of said ports as jets of water.

A spray head for a pre-rinse assembly comprising
- a housing having an inlet for a flow of water;
- a diffuser disposed in said housing on a longitudinal axis of said housing, said diffuser having a base disposed in said housing to define a transverse chamber therebetween in communication with said inlet for receiving the flow of water and a circumferential wall extending from said base to define an annular chamber therebetween in communication with said transverse chamber to receive the flow of water, said wall having a slot extending angularly therethrough and being in communication with said annular chamber to direct a jet of water therethrough;
- an impeller mounted in said diffuser for rotation therein, said impeller having a plurality of circumferentially disposed fins thereon for impingement of the jet of water passing through said slot thereon to cause rotation of said impeller, said impeller having three tabs disposed circumferentially thereof and transverse to said fins;
- and
- a discharge cover mounted on said housing in facing relation to said impeller, said cover having three ports for discharging water therethrough, said ports being disposed relative to said tabs whereby a respective tab covers a respective port to prevent passage of water therethrough during rotation of said impeller while the other of said tabs are spaced from the other of said ports whereby two streams of water are discharged from the spray head at all times during operation of the spray head.

A spray head for a pre-rinse assembly comprising
- a retainer having an inlet for a flow of water;
- a discharge cover mounted coaxially of said retainer and having a plurality of ports for discharging water therethrough,
- a diffuser disposed coaxially between said retainer and said discharge cover, said diffuser having a base defining a transverse chamber with said retainer and in communication with said inlet for receiving the flow of water and a circumferential wall extending from said base defining an annular chamber with said discharge cover and in communication with said transverse chamber to receive the flow of water, said wall having at least one slot extending angularly therethrough and being in communication with said annular chamber to direct a jet of water therethrough;
- an impeller mounted in said diffuser for rotation therein, said impeller having a plurality of circumferentially disposed fins thereon for impingement of the jet of water passing through said slot thereon to cause rotation of said impeller, said impeller having a plurality of tabs disposed circumferentially thereof and transverse to said fins, said tabs being disposed relative to said ports whereby a respective tab momentarily covers a respective port to prevent passage of water therethrough during rotation of said impeller thereby effecting a pulsating stream of water through said respective port.
